As the Swine Flu outbreak spreads from Mexico across the border to the US, bloggers are asking questions about the possible links between the outbreak of this new influenza strain and industrial hog production in Mexico. At present, the Mexican authorities are reporting that 81 people may have died following infection and over 1300 people have been admitted to hospitals for testing. 11 people in the US have been infected with the new H1N1 strain, which shares genetic material from human, avian and swine influenza viruses.

At present, mainstream news sources are focusing on reporting possible new cases (in UK, NZ) and reporting on statements from the WHO and the CDC, but have paid little attention to the source of the outbreak. Bloggers, however, are already exploring the links between Mexico's industrial hog production industry - Smithfield Foods in particular - and the emergence of the new viral strain.

Mexico accounted for 1.6% of the world pig stocks in 2007 - that's 15.5 million pigs. The largest hog producer in the world, Smithfield Foods owns two subsidiaries in Mexico, Norson and Granjas Carroll de México, which produced 467,000 and 950,000 hogs respectively in the 2008 fiscal year.

The second of these subsidiaries, Granjas Carroll de México, is based Perote in Vera Cruz state where the outbreak originated. Biosurveillance, which has produced this timeline of the outbreak, reported the following from local residents:

Residents believed the outbreak had been caused by contamination from pig breeding farms located in the area. They believed that the farms, operated by Granjas Carroll, polluted the atmosphere and local water bodies, which in turn led to the disease outbreak. According to residents, the company denied responsibility for the outbreak and attributed the cases to "flu." However, a municipal health official stated that preliminary investigations indicated that the disease vector was a type of fly that reproduces in pig waste and that the outbreak was linked to the pig farms. It was unclear whether health officials had identified a suspected pathogen responsible for this outbreak.

Tom Philpott at Grist has linked this to reporting in the Vera Cruz-based newspaper La Marcha that blames Granjos Carroll for the outbreak, highlighting inadequate treatment of massive quantities of animal waste from hog production.  Paula Crossfield at Civil Eats, and Paula Hay at Peak Oil Entrepreneur are raising the same questions, and asking why the mainstream media isn't exploring the CAFO connection with Smithfield's Mexican operations.

At the Huffington Post, David Kirby reports that CDC and USDA officials will likely investigate industrial hog operations as soon as they arrive in Mexico to investigate the sources of the outbreak. Kirby's piece reports on researchers' concerns that large-scale indoor animal production facilities have become breeding grounds for existing and emergent viral pathogens, including E. Coli, Salmonella and MRSA.

We know that hog workers in Europe and North America are far more likely than others to be infected with potentially lethal pathogens such as MRSA (Methicillin-resistant Staphylococcus aureus), drug-resistant E. coli and Salmonella, and of course, swine influenza. Many scientists also believe that people who work inside CAFOs are more at risk of contracting and spreading these and other "zoonotic" diseases than those working in smaller-scale operations, with outdoor pens or pasture and far lower animal density.

But until now, hog workers with swine flu have rarely gone on to infect other people, save for close family members. And that is why this new strain of swine influenza virus is so vexing - and alarming. It seems to spread quite easily through casual human contact. (Huffington Post)

I'm sure we will hear more on this shortly, as officials start to investigate the source of this outbreak. More questions are bound to asked about whether we can afford the risk to human health presented by industrial farm animal production. For more on these risks of , check out this comprehensive report from the Pew Commission.

The source is all over the blogosphere; search for:
smithfield "swine flu"

It has not been substantiated, as far as I know, but there was quite a bit of pollution, and I have seen photos and videos taken from the air of the same thing happening in the United Sates, due to non-regulation of excrement from farms with hundreds of thousands of chickens, or tens of thousands of pigs.

There is more to be learned. Just remember that the toxic vegetables (spinach or lettuce?) that killed quite a few in the United States were due to excrement run-off in farm irrigation canals that got absorbed into the inside of the green leaves, where it could not be washed off.

I watched the news yesterday & at no point did anyone mention the source of the outbreak. Tho they did say they didn't think it was seroius enough 2 warrent a ban on travel" I thought then why are they spending money 2 produce masks & pills... I thought I can't be the only one noticing that they don't mention the realitys of this situation...
The news said "We will do genetic testing 2 find answers... I thought where's the mention of the source?? & he goes & says that!?? I've seen this be4 in Government.

Interesting about the name change (I suppose they used the Hebrew terms). You may notice that other well-known flu epidemics were the "Spanish" flu of 1918 that killed many millions, and the recurring "Asian" flu. It is possible that Israel is normalizing the discussion of this potential pandemic by referring to the source of first discovery, as with the other two examples. Also, if you look at the reporting on this, the flu is not a pure swine flu, but combines the genetics of human, avian, and pig flu. It could promote a more informed public response and growth of understanding not to use an inaccurate label. "Mexican flu" is accurate by referring to the point of first observance, while "swine flu" is somewhat inaccurate.

There were some interesting articles about the source of all this being unclean practices in an American-owned pig "farm" in Mexico, joint-owned by Smithfield. The claim is that contaminated pig run-off was being dumped in the drinking water. It would not surprise me at all to hear that all this could have been prevented. The real cause? Overcrowding of people, factory farming to feed the masses of humanity, and human nature which gets careless inevitably. Hopefully this will turn out to be mild even if it does become more widespread. Last point: the millions dying yearly of (preventable) diarrhea and malaria make this current outbreak look like a walk in the park.

After the first case of Swine Flu was reported in Israel, their government changed it to "Mexican Flu" because Jews consider pigs to be unclean and they did not want to hurt the sentiments of Jews. So will the rest of the world from now on have to walk on egg shells in fear of being branded Anti-Semite for using the term Swine Flu?

The Flu originated in Pigs, who incidentally happened to be in Mexico. It did not ORIGINATE in a citizen of Mexico!
